Otto Bock: Mobility is key High-tech prosthetics for the world market require a close-knit network of skilled and expert partners. Otto Bock’s network consists of several hundred different contacts for R&D, design and manufacture worldwide, but more than 50% are located in Austria. Examples of trusted partners in Vienna are Merten, PIU-Printex and the Medical University. Otto Bock is market leader in medical technology focusing on arm and leg prostheses. Its Viennese subsidiary, Otto Bock Healthcare Products GmbH, is one of the Group’s most important research and development centres. Otto Bock’s goal is to enhance the quality of life for people with disabilities by giving them improved mobility. Diseases, particularly narrowing of the blood vessels as a result of diabetes mellitus, togetPhoto: © PIU-Printex her with serious accidents in all age groups still often lead to limb amputation. Otto Bock helps to ensure that the replacements are as natural as possible in function and appearance. This requires in-depth understanding of natural movement processes combined with specialist orthopaedic knowledge, the application of novel computer technologies and the use of modern materials such as carbon and silicon based substances.

Knee joint revolutionises leg prosthesis Developed and produced in Vienna, the C-Leg® knee joint is controlled by microprocessors and is a milestone in leg prosthetics. Its users appreciate the closest approximation to a natural gait achieved so far. The application requires state-ofthe-art sensors in the knee joint:
printed circuit boards are the crucial core components of the electronic assemblies involved. Otto Bock’s supplier in Vienna, PIU-Printex GmbH, has great technical experience and can be flexible in response to fluctuating demand, making it an ideal partner. Specially equipped circuit boards provide the electronic control and regulation for Otto Bock’s arm and leg prostheses.

World class with myoelectrics The myoelectric DynamicArm® elbow system was developed in Vienna. Its processes are very similar to natural movements. Muscle impulses are transmitted by sophisticated electronics to the parts of the prosthesis to be moved. Another special feature of the elbow joint is its strength: it can lift up to 6 kilograms and exert some 60 kilograms of tractive force. A milled highly durable aluminium component produced by Peter Merten GmbH, a Viennese company with a long tradition of high precision machining, is of key importance. The part supplied by Merten ensures that the quality and reliability of the DynamicArm® will be sufficient to meet the strains and stresses of everyday life.

What the future holds in store The Vienna General Hospital is one of Europe’s biggest hospitals and a leader in the field of neuromuscular reconstruction. Working closely with Professor Manfred Frey, who heads the Clinical Department for Plastic and Reconstructive Surgery of the Medical University of Vienna, Otto Bock has developed a mind-controlled arm prosthesis. For the

novel arm prosthesis to be controlled by the nerves originally responsible for moving the arm, the remaining nerves have to be transferred from the residual limb onto the chest. Prof. Manfred Frey and Prof. Oskar Aszmann are the only surgeons outside the USA who are capable of this selective nerve transfer. A young Styrian is the first and so far only user of the intelligent arm outside the USA. The most recent innovation from Otto Bock is the continuing development of this approach into the touch-sensitive hand. Microsensors on the index finger register temperature, vibration and pressure, and a microchip translates the results into interpretable signals that can be felt as physical sensations. www.ottobock.at www.piu-printex.at www.merten.at www.meduniwien.ac.at
